AF5, journal integration, security

Pre AF5 you could hide forums, and if you used the what's new module it would obey (by default) the security settings. In other words if you weren't a part of the group what's new would not display your post.

Fast forward to Af5, which unless something has changed, the what's new module has been retired and replaced with the journal module.

So the question what are the rules for how AF5/Journal handles security with regards to the journal entries made by groups/forums that are security by group membership (right now I currently referring to AF5 forums running in a non-social group mode).
